different work stations, while the flexible arm is able to operate over a working radius of 3 m.
The machine is supplied as standard with an electrical control panel, IP65 protection, made up of:
• ON/OFF switch;
• magneto-thermal protection (for electric motor);
• differential pressure switch with simultaneous temperature control;
• machine power supply signal (white light);
• machine on signal (green light);
• clogged filter signal (red light).
The filtration section then according to the versions is as follows:

MFE-HD unit supports 2-3 m arms; these can be of the following type:
ARMOFLEX
The internal supporting structure is realized with reinforced steel
billet pipes and 6061 aluminum alloy components after CNC
worked for T6 in physical state, then anodized to ensure durability
despite continuous exposure to fumes.
The flexible covering pipe is a multilayered PVC to guarantee the
protection from eventual sparks and a high temperature resistance.
The extraction hood is round shape for a maximum efficiency of
extraction, complete of manual damper for the airflow calibration,
anti-intrusion mesh and bridge-shaped handle.
ARMOTECH
The internal supporting structure is realized with reinforced steel
billet pipes and 6061 aluminum alloy
components after CNC worked for T6 in physical state, then
anodized to ensure durability despite continuous exposure to fumes.
The rigid pipe in aluminum allows a high lightness.
The suction hood is round shape to provide a maximum efficiency
of extraction, complete of a manual
damper for an airflow calibration, safety anti-intrusion grate and
handle.
